SPECIFICATION forming part of Letters Patent No. 243,505, dated June 28,1881.

Application filed April 15, 1881. (No model.)

Io all whom 'at may concern:

Be it known that I, GEORGE OARNELL, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Brick-Machines, of which the following is aspecification.

My invention relates to certain improvements in that class ofbrick-machines in which the clay is forced from the filler-box byaplunger into a series of molds beneath said tillerbox, my improvementsrelating to details in the 'construction of the machine, too fullydescribed hereinafter to need preliminary expla nation.

In the accompanying drawings, Figure 1, Sheet 1, is a perspective Viewof the machine; Fig.- 2, Sheet 2, a longitudinal section of the same;Fig. 3, Sheet 3, a sectional plan ou the line 1 2, Fig. 2; Fig. 4, asectional plan on the line 3 4, and Figs. 5, 6, 7,8, and 9, Sheet 4,detached views of parts ofthe machine.

A is the frame of the machine; B, the vertical clay-box; D, thefiller-box on one side' of the same; and E the main driving-shaft,passing vertically through the center of the claybox, and rotated bypower derived from any adjacent shaft. Y

To the filler-box D is adapted a plunger, a, rendered verticallyadjustable on a rod, b, by means of a nut, b, adapted to the threadedlower end of the rod and bearing on the top of a hollow lug, 112,011 theplunger. The rod b is adapted to a guide on the clay-box, and isconnected by means ot' a link, c, to an arm, (l ,on a rock-shaft, d, thelatter being adapted to bearings on the frame A, and having a forkedarm, d?, a pin, d3, which engages with a slot in a rod, e, lullig to a`yoke, F, which slides in guides e on the top ofthe frame, and is actedupon by an eccentric, F', on the main shaft E, so that as said shaft isrotated a vertical reciprocating movementwill be imparted to the plungera. p

The yoke F consists of end bars,ff, and connecting-rods f f', and inorder to permit the movement of the eccentric F without imparting anylateral movement to the yoke, the said eccentric is adapted to act uponthe end bars, f, of the yoke only, and the latter have segmentalrecesses f2 formed in them to prevent the eccentric from becoming jammedbetween it rotates. (See Figs. 1,

effected by manipulating a lever, G, hung to the arm d2, the short armof this lever having a projecting pin, on which the rod c rests.

The shaft E has within the clay-box the usual tempering blades or arms gand two pressers, H and I, the presser H being located immediately abovea slotted partition, H', in the clay-box, andthe presser I being at thebottom of said box. The presser H has curved plates h, which, as thepresser revolves, tend to force the clay downward through the slots h inthe partition H. Stones or other hard particles which are too small tointerfere with the formation of the brick or the operation of thepressing mechanism will be forced through the slots h with the clay, butlarger stones or other foreign matters will be carried around by theblades lz, as they cannot pass through the slots. In order to dispose ofthese larger particles and prevent them from accumulating on the top ofthe partition I make the slots in the latter in the form of scrolls,there being in the present instance in the partition four independentscroll-slots, terminating, respectively, in the four corners of theclay-box, as shown in Fig. 3, so that stones, under the inuence of thesescroll-slots,will,as they are carried around by the blades h, be thrownoutward, and will finally be deposited in one or other of the corners ofthe box, out of the path of the blades h, the accumulated stones in thecorners of the box being removed at intervals by the attendant.

The presser I, Fig. 4, consists simply of a camblade, adapted to forcethe clay through a side opening, t', in the clay-box and into thefiller-box D, where it is acted upon by projections a' of the plunger a,and is forced through the grating D' at the bottom of the filler-boxinto the series of molds m beneath said grating. The molds m arepreferably of a character similar to that described in a separateapplication led by me on the 9th day of February, 1881, although mymachine is adapted IOO for use in connection with any mold having aseries of openings side by side, so as to form a series of bricks ateach operation of the plunger.

bars a', which are adjustable in respect to the frame of the machine, inorder that a proper joint between the tops of the molds and the bottomof the filler-box grating D' can always be maintained, the adjustment inthe present instance being effected by set-screws n2. When one set ofmolds is filled it is pushed from beneath the ller-boX and onto aplatform, J, by the action of a fresh set of molds on a carriage, K, thelatter being adapted to suitable guides in the bars a', and beingactuated by a cam, L, on the shaft E. As soon as the new set of molds isadjusted to its place beneath the filler-box the carriage is retractedby the action of the weight L, and a fresh set of molds is slippedlaterally onto the said carria ge priortoarepetition of theoperation.The

cani L acts upon a spring, p, on the carriage K, as shown in Fig. 7,this spring bearing upon a central set-screw, 19 but being free to yieldat each end, so as to lessen the shock caused by the first con tact ofthe cam L, the adjustment ofthe setserew p serving to govern thelimitofmovement of the carriage K by the cam L. so that the depositing of themolds m exactly under the center of the filler-box is insured. As themolds are pushed from under the filler-box the bricks are leveled by theaction of the plate s, which is let into the filler-box grating, andforms part of the bottom edge of the same. (See Fig. 8.) It will beobserved that this cutting-plate s overhangs the outer edges of themolds, so that when said molds are pushed from under the ller-box theplate commences to act upon the surface of thebrick at some distancefrom the edge ofthe same, and there is not that tendency to tear theclay away from the end of the mold which exists when the cutting-platecommences to act upon the eXtreme edge of the brick. As the molds passfrom under the filler-box the upper faces of the bricks are moistened bya stream of water from a pipe, t, communicating with a reservoir, t', atthe end of the filler-box, and the moistened faces of the bricks arethen smoothed by the action of a scraping-plate, w, secured to the sideof said filler-box.

The molds m rest upon rollers n carried by By providing the plunger awith projections a', adapted to the openings in the grating D of theiiller-box, almost the entire body of clay in the filler-box is forcedtherefrom into the molds on the downward stroke of the plunger, so thatthere is not left in the filler-box or grating a large mass of clay,from which the bricks must be forcibly separated on pushing the moldsfrom beneath the filler-box. The tearing of the clay from the molds andthe formation of defective or imperfectly shaped bricks is thusprevented.

I claim as my invention- 1. The combination of the shaft E and itseccentric Fl with a sliding yoke, F, having recessed end bars, f, as setforth.

2. The combination of the plunger-rod b, rock-shaft d, having arm d2,with pin d3, the yoke F, the slotted connectingrod e, and the lever G,hung to the arm di", and adapted to elevate the rod c, as set forth.

3. Thecombination ofthe clay-box, the shaft E, the presser H, and thepartition H', having scroll-slots h', as set forth.

4. The combination of the mold-carriage, having a spring, p, with theoperatingcam L, adapted to act upon said spring, as specified.

5. The combination of the operating-cam L with the mold-carriage K, itsspring l), and set-screw p', as set forth.

6. The combination of the molds with a ller-box, having on its underedge a cutterplate, s, adapted to overlap the outer edges of the molds,as set forth.

7. The combination of the filler-box with the sprinkling-tube andscraper-plate, whereby the surfaces of the bricks are smoothed as themolds are moved away from the ller-box, as specified. f

8. The combination of the filler-box, its grating D', the molds, andmechanism for moving the molds beneath the box, with the plunger a,having projections a', adapted to the openings of the filler-boxgrating, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
